Taken together, the combined ESP and LUMO analyses establish a clear trend in the PnB donor strength of 3 > 2 > 1 when interacting with the same acceptor, consistent with the expected Lewis acidity order of Sb( v ) > Sb( iii ) > P( iii ). 22 b Guided by computational predictions of PnB donor strength, we initially pursued the synthesis of polymeric PnB donors via copolymerization of monomers 1–3 separately with styrene.
